Prefabrication both on and offsite is a growing trend offering multiple benefits in quality, safety and construction efficiency.

Larger cranes are needed to facilitate this move so now is the time to gear up for it. As Mammoet said, “assurance is needed that today’s project planning will match tomorrow’s equipment.”

To this end, the latest to join the global Mammoet fleet of heavy lift cranes is a 2,500 tonne capacity Liebherr LR 12500-1.0 lattice boom crawler crane, the first of its type for the Netherlands-headquartered global giant.

Looking at the heavy lift fleet of series-production cranes it sits between the 3,000 tonne capacity Liebherr LR 13000 and the 1,350 tonne capacity LR 11350, also a Liebherr.

Energy and infrastructure

In the energy sector this and other large cranes will be increasingly important in shortening construction time, improving cost effectiveness on newbuild projects, and reducing downtime in upgrades and planned maintenance shutdowns.

Wind turbines are still getting bigger and large ones are becoming the norm. Offshore turbine nacelles weigh 1,000 tonnes and tower sections double that. Heaviest turbine components, however, are the monopile and jacket type foundations, weighing 3,000 tonnes.

A 200 metre hook height is possible on the LR 12500-1.0 using a 100 metre main boom and 108 metre luffing jib.
